The NSF East Asia and Pacific Summer Institutes (EAPSI) provide U.S. graduate students in science and engineering first-hand research experience in Australia, China, Japan, Korea, New Zealand, Singapore, or Taiwan. They also serve as an introduction to the science and science policy infrastructure of the respective location, orientation to the culture and language, and aim to help students initiate scientific relationships that will better enable future collaboration with foreign counterparts.

The institutes last approximately eight weeks from June to August and are administered in the United States by the National Science Foundation (NSF). The National Institutes of Health (NIH) co-sponsor the 10 week institutes in Japan. Applicants must propose a location, host scientist, and research project that is appropriate for the host site and duration of the international visit.
